Well hell, as long as people are starting to give serious answers, here we go... I dated a girl back in college. We even talked about marriage even though we were young and stupid. We broke up and went our separate ways after graduation. Years later, we become friends on Facebook. Turns out she married one of my friends from college and they had 2 kids together. Now I'm married and have a couple of kids myself. Last year, we went to a wedding of a mutual friend from college. The 4 of us sat at the same table at the reception. We had so much fun, we ended up going out afterwards and having a blast. My wife and the ex really hit if off and had a lot of fun (mostly at my expense) making fun of all my bad habits and weird idiosyncrasies. We're going to a birthday party next month and the first thing my wife wanted to know was if she would be there again. You see......this is typically how adults act.
So I just talked to the girl. Her Husband is away for a bit. She and I talked tonight. Living in a crazy expensive place in PVR. $7200/month. As far as me? I'm only on the outside...
Many people have "spheres" of friends and acquaintances. People often date people within their sphere, which means a Venn diagram of friends and acquaintances often overlap between the people dating each other. Sometimes they overlap a little bit, and sometimes they overlap a lot. Because of this, people often date people in those overlapping groups of people. So if you're dating someone, it is extremely common for them to date someone else that you know after you've broken up. It may be a close friend, or an acquaintance, or a friend of a friend. Its sort of just human nature and proximity. I wouldn't get bent out of shape about it, especially 10 years later.
Two different girls. PVR is from college. Other is from a decade ago. Here's where y'all miss the point: The Aussie has hit on 3 guys I personally know. That's not cool. Especially when I told her. Who does that? When I think about her friends back then... Well, ****. There was one I made a move on. ****... Y'all are right, but I still feel I can be pissed about it.
This is the total disconnect I see in this whole ordeal. You loathe this (I assume 45+ year old) woman because she is flirting with a few of your buddies. Yet you wrote this: "Again, I've no dog in the fight. My friend told me about it. I said I'd prefer you not because of the awkwardness of someone who I have years of a track record with, but he can do what he wants.". So... if your friend wants to take it to another level, he can do what he wants, but you loathe the 45+ year old woman for flirting.
